Exploring the Role of Fertilizers in Agriculture and Their Environmental Impacts

Matin Qaim, Director of the Center for Development Research at the University of Bonn, examines the various aspects comprising food security, namely local and global supply chains, the generation of income for local farmers, investments in the production of nutritious foods, as well as accounting for climate externalities. Attaining food security has become even more difficult given the disruptions around the pandemic, rising inflation, and the failed Black Sea grain deal. He asserts that small-scale farming and agroecological approaches are not necessarily low-tech and that certain technologies, if applied correctly, can assist smallholder farmers.
